Suppressing Charged Cation Antisites via Se Vapor Annealing Enables p-Type Dopability in AgBiSe

Cation disordering is commonly found in multinary cubic compounds, but its effect on electronic properties has been neglected because of difficulties in determining the ordered structure and defect energetics. An absence of rational understanding of the point defects present has led to poor reproducibility and uncontrolled conduction type. AgBiSe
